In 1879 Siemens sold the first electrical installations for ship lighting to be used for three German ships Hannover, Theben and Holsatia. These contracts 135 years ago are regarded as the official start of the Marine activities. In 1886 the Siemens-built Elektra was the world’s first ship with an electrically powered propeller (4.5 kW electric propulsion motor). In 1904 Siemens supplied all the electrical machines for three submarines of the Russian navy and in 1906 for the first German submarine. Since then, for approximately 110 years, Siemens has played a leading role in the design and construction of electric Propulsion Systems for submarines. For decades DC double motors together with armature and exciter current choppers dominated submarine propulsion. In 2000 Siemens delivered the first permanent-magnet synchronous motor with integrated power converters and PERMASYN-type propulsion motor/ drive for a submarine to a yard. The impressive reference list of Propulsion Systems for the last approximately 50 years can be found on page 24. Propulsion Systems for conventional submarines consist of: • A propulsion motor for direct drive of the submarine (directly coupled, without reduction gear) • Inverters/converters for adapting/converting voltages (e.g. choppers or power inverters/converters) • Switchboards for switching and protection of the Propulsion System and ship mains • Propulsion control with open- and closed-loop control functions for monitoring and operation of the Propulsion System components 3 General General requirements information and integration Propulsion Solutions for conventional submarines allow Cutting-edge technologies required the use of stored or generated electrical power supplied Propulsion Systems for submarines are highly specialized directly or indirectly (via batteries) from DC sources such drive and switching plants in the DC low-voltage range as Air Independent Propulsion (AIP) systems for propulsion (up to 1,000 V DC) for high power and heavy short-circuit purposes.

In both indexes, the subject or author (given in bold print) is followed by the title of the article; then (in bold again) the issue and page number, separated by a dash. For example, 1-10 is Issue 1, page 10; 85-12 is issue 85, page 12; and so on. See the table on pages 2 & 3 for the dates of each SubCommittee Report issue number. This is just a general index in that only article titles and authors are referenced. A normal index would include all references to particular subjects found within articles; that is not the case here. For example, just about any article written on building a model submarine will include a detailed description of the approach taken to constructing the hull or ballast tank, but the subject headings “Hull/Hull Layout” and “Ballast System/Tanks” only list articles that are specifically about those subjects; more, of course, will be found in articles and columns under other subject headings, which include the names of specific submarines and vendors. When there is overlap among topics in an article, it may be listed under more than one subject heading.

  • British Submarine Policy 1853-1918 Michael Wynford Dash a Thesis
    y_< I British submarine policy 1853-1918 Michael Wynford Dash A thesis submitted for the degree of Ph. D. at King's College, University of London Department of War Studies 1990 BIBL. LOND[h. .:, UNIV.. ABSTRACT O Abstract The submarine is used as a case study to examine British attitudes to developing naval technology. Study of the Royal Navy's submarine policy suggests that the Admiralty was less conservative and more able than is often supposed. The British were thoroughly conversant with all significant developments in underwater warfare from 1853. There was an early, if abstract, appreciation of the potential of submarine boats, but a distinction must be drawn between adequate technical assessments of early submarines and inadequate appreciation of the strategic consequence of developments in submarine warfare. Development of British policy was greatly influenced by restrictive agreements concerning the type of vessels to be built by the Vickers arms firm, by the character and personal beliefs of successive Inspecting Captains of Submarines, and by the Royal Navy's decision to resume partial responsibility for coast defence from the Army. British experience is put into context by a study of the submarine policies of other powers. The importance of the coastal submarine to Imperial defence is discussed, the patrol submarine's influence on the British policy of blockade is assessed, and the failure to anticipate unrestricted submarine warfare examined. In the final chapter, the performance of RN boats in the Great War is set against pre- and post-war submarine policy.

  • Early Torpedoes and Their Conservation in the Deutsches Museum, Munich
    I. međunarodna konferencija u povodu 150. obljetnice tvornice torpeda u Rijeci i očuvanja riječke industrijske baštine 187 EARLY TORPEDOES AND THEIR CONSERVATION IN THE DEUTSCHES MUSEUM, MUNICH Dr. Jobst Broelmann Curator of the Maritime Department, Deutsches Museum, Munich, Germany FISH TORPEDOS - LITTLE SUBMARINES The history of the torpedo of Robert Whitehead and his cooperation with Giovanni Biagio Luppis has been outlined in several publications.1 Reflecting the history of the automobile torpedo it may be of some interest to point out some possible connections and links between the ideas of Luppis to the contemporary efforts of the german inventor Wilhelm Bauer. From about the 1850s both inventors had been experimenting with small, unmanned submarine automobile vessels. Bauer had originally the idea to copy and imitate the diving actions of a seal by constructing an “iron seal”, that was to be propelled by human power with the purpose to attach charges to enemy ships. Bauer started with a small model of about 700 mm length before his submarine “Brandtaucher” was built under considerable difficulties without sufficient financial support. The Brandtaucher had a length of about 8 m, and a beam of 2 m. It was propelled by the power of two men which was tansferred via a gear system to a propeller.2 After a severe set back of his “Brandtaucher”, which sank with a crew of three during the first diving experiments in the harbour of Kiel in 1850, he was forced to improve his ideas by again using smaller, unmanned test models. These models had also the purpose of representating his concept to possible supporters, mainly in the european navies of that time.
